EGT cool down time?

Hey guys so I haven't been able to get an egt probe yet but don't like to shut the truck right off without cooling down first. So I guess I'm looking for a general answer from the guys who have a gauge already. About how long does it take for EGT's to fall to a safe level?

Usually less than a minute for mine to get down to 350.

About 15-30 seconds is all I really wait for it to get down there... Just give it some time after you stop, and you will be fine!

i was pretty surprised how quick my truck cools down. on the last bit of road driving home i take it real easy and by the time i get in my driveway it is sometimes below 350 already. if it isn't then it is with in about 5-10 sec. but if actually out driving it can take about 15-30 sec depending on how hard you drive it. towing of course takes a lot longer ive only towed heavy (well sorta heavy at 6k) once since egt gauge install and it took a couple mins till i felt comfortable enough to shut it down. but you also have to take into account for mods such as intake, exhuast, tunes and what not.

I use the ISSPRO turbo temp monitor from "diesel manor" and as the other guys stated it only took a few seconds or a few minutes (depending of how hard you drive the truck). Mine is set to shut off the engine at 300* and sometimes the turbo is so cool at my arrival destination that shut off right away. 15-30 seconds is more than enough for normal driving. I hope this help you.

So are you all thinking that when EGT falls off that quickly that the turbo components are that cool also?
